struction of the s lice yforming the subject mat-ter of my app lcationfor rail splice filed November 18, 1908, Serial No. 463,329.

The fpresent invention contem lates a' having an upturned flange at eachlongitudifnale'dgethe. inner or facing surfacesjof the 'said fl tute'anoverhang .for receiving splice-bars placed at eachqside vof the rail oneof said portionsfadapted to 'tone ofthe undercut ilanges, 'provision.being made to prevent ongitudinalmovement of" the two splice# 36harsrelativeto the hase but this will be moreclearly andffully explainedhereinafter. To the' end that myinvention may be un-v d ralwing4 inWhichz.

Fig. 5- 1-sa vertical 'transe' '-5, Therail is represented the letter and ventinglongitudinal movement of saidfparts anges being undercut so'as toconsti?vv dorst-ood I have provided the accompanying B .isv'a basefplateconstituting a support for the rail. Sa1d plate is kprovided with anup'- resented by C and C "Whose -in ner or facing surfaces 4are undercutso that their corners overhang the base as shown at a. I have shown inmy former application abase-plate havin aflange at one edge there- 'ofundercut in t sjmanne-r While the other Aedge of said plate" is providedwith an up'-- .n-'ardly' extended flange as la part thereof to mclose.one sideof the' rail. I have found .that `although .such a form can bemade be-v Q ln'rolling millsyone that is very simple I5 in construction,and of low cost. object' is to provide a supporting tween properlyconstructed rolls that a form |such as shown and described in thepresent instance is mucheasier to form and some of the operations can beeliminated thus reducing the cost of manufacture.

'At each side of the rail, which is positioned latv about the middle-ofthe plate is a s lice. bar., These splice-bars are indicated y D -and Dand are duplicates in that they are bothy sheared or out' from a singlebar formed between. rolls.- Each. consists of a vertical [extension anda substantially horizontal extension the former adapted to it snuglybevturned flange at each longitudinal edge reptiveen the head and baseofthe rail, the latter adapted to rest upon the base of the rail; and

each bar is extendedbeyond the rail-base and lies' between the rail andthe flanges C and C of the base before described. The extended edgeofthe bar-D is provided with 'an angled face to fit the undercut surfaceof the flange C andin consequence of being duplicates the opposite oneDis necessarily of y the sameform although a particular form of thissaid splice-bar D isnot important as to v ythe angled face mentioned butslnce bothare cu-tfrom the same bar it will necessarily be of the formshown.

At one or more places the splice-bars are provided With notches in theiredges adj acentto the flanges C and C. One of these notches is shown inFigs. 4and' 5 at E and also in Fig. 7 at E. They are formed in the edgesof the horizontal extensions which lie adjacent to thev llanges C and Cand immediately be- -neath them inthe base plate holes F are punched andin theholes and the" notches C "are inserted Wedge shaped bolts G Whoseand are provided with nuts J to tighten them; the form and arrangementof thie type of bolt having beenfdescribed in my. former per threadedends-extend through blocks.

.make the., advantage to be gained lfrom the present arrangementfullyunderstood.' Since the bolts are in fact Wedges'and bear against rthe undercut 'flange C they are' caused -to move toward the rail as thenuts J are tightforce that member tow-ard `the rail thereby moving therail toward and against .the splice-bar D carrying that member firmlyagainst the overhanging flange C, vvhichsaA curely holds it so it canhave no vertical movementwhatever. Having now provided for preventingvertical movement of the bar D it is next important that there be nolongitudinal movement thereof relative to the base-plate. This isprovided for in the use of the Ablocks K whichhave a position Within thenotches E alreadyT mentioned so that in effect the splice bar D and thebase plate are as though they-Were one member or unit While giving'theadvantageof easy construction by being separate parts. j

The bolts G by having their position Within the notches E of thesplice-bar D prevent longitudinall movement of that member so y that allofthe various parts are in eiiect locked relatively. i the blocks K restupon the flange C so that said blocks cannot drop through and leavetheir positions.

It is Well understood that the side thrusts of the Wheels-of the trainupon the rail tends to rack the splice and its parts With the resultthat the parts become loosened and the splice-bars in the ipresent casein the absence of some form of holding means Would receive more or lessmovement in the direction oi' their lengths and relative to'thebase-plate Which Would result inydisarranging the parts but since thebolts G on the one hand and the members or blocks K on the otheihandeiiectivelyloclr the splice-bars relative to the base there canvbe nomovement of any of the parts and since there is no movement of thesplice-bars there is nothing to cause the bolts L to become loosened.

My splice as constructed isvery easily ash o positesides of the device,as shown in Extensions or lugs K of when tightened all of the parts arefirmly clamped in proper relation; the base-plate being afterwardproperly spiked to the ties in the usual manner.

The holes F andl F in the base may be punched so that they coincide withthe inner faceof the flanges C and C as shown in Figs.

and 7 or for convenience in punching they ray be placed slightly inwardfrom the ilanges Where they can be more conveniently reached by thepunch and Without damage to the ilanges in which case the block K isprovided with an oil-set as shown in Fig'. 5,

i l and a member M, Fig. 7, may be placed-'be cned and in bearingagainst the splice-bar D i tvreen the bolt G and the flange C to takethe pressure ofsaid bolt, this however is merely a structural detail.

All the parts of my improved 'splice may be formed between rollsincluding the meinbers K which may be obtained by rolling a bar of thedesired form of cross section from which pieces. ot4 the proper size canbe cut or sheaied to lit thelioles F.

rlhe Whole purpose of my invention, as may be seen is to form the baseand splicebars of separate parts acting in the capacit): of a singlemember or unit and to provide a form of means by which both splice-barsare absolutely prevented moving in a longitudinal direction relative tothe base-plate.
